    Assignment:Find the solution set of inequality e^ = -0.15 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
         e ^ < x * 3.14 / sqrt ( 1 - x ^ 2 )         (1)
         x * 3.14 / sqrt ( 1 - x ^ 2 ) >= -0.15         (2)
        From the definition field of √
         1 - x ^ 2 ≥ 0        (3 )

---

    From inequality(1)：
         x < -1 或  x ＞ 0
    From inequality(2)：
         x ≤ -1 或  x ≥ -0.047716
    From inequality(3)：
         -1 ≤ x ≤ 1

---

    From inequalities (1) and (2)
         x < -1 或  x ＞ 0    (4)
    From inequalities (3) and (4)
         0 < x ≤ 1     (5)

---

    The final solution set is :
         0 < x ≤ 1
